ng said, and if price is not so much of a concern to you, and you want a thicker watch with some additional features such as a thermometer and a compass, you might want to look at the G-Shock Mudman models. However, while all Mudmans are solar powered, not all of them feature multi-band 6 atomic timekeeping like this one.SOLAR BATTERY CHARGEDo not get frustrated if at first you receive this watch and the Battery Power Indicator will not go to high while indoors and exposed to light. That is what happened to me the first 2 or 3 days trying to raise the charge from medium to high near an indoor window. My advice is to keep a positive attitude about it. There is nothing wrong with the solar battery. Simply get the watch into outdoor sunlight for a few hours. I finally wisened up and did that on the third day, and the Battery Power Indicator went to high. That was 34 days ago, and it has been on high ever since.OPERATIONThis watch is extremely simple to operate. It has no unnecessary thermometer or compass which, to the average person, are not worth the hassle of setting up, especially since the accuracy of those features is always in question.I like the front button for illumination of the light. Many G-Shock models have no front button instead utilizing the upper right side button for light illumination.Further, I like the ability to scroll both east and west through the 48 city codes this watch offers. Not all G-Shocks can scroll in both directions. Sometimes they are limited to eastward scrolling due to configuration of the module with the style. But the capability of both east and west scrolling is far less clumsy.If you want to further check out operation, I suggest researching the online Operation Guide where you will find very clear and concise product information.Important Tip: The times displayed in the Timekeeping Mode and World Time Mode are linked. Because of this, be sure you select a Home City (the city where you normally will use the watch) BEFORE you set the time and the date. Sometimes people do not read the Operation Guide and initially get hung up on operation not realizing this.INSCRIPTIONon Stainless Steel BackST.

For comparison of those types, I have described each of them below:1. Acrylic crystal is an inexpensive plastic that allows shallow scratches to be buffed out.2. MINERAL crystal (this watch) is composed of several elements that are heat-treated to create an unusual hardness that helps resist scratches.3. Sapphire is the most expensive and durable crystal, approximately 3 times harder than mineral crystals and 20 times harder than acrylic crystals.PHOTOSThe 5 photos included with this review are not mine.

GOOD. I'm writing it because just got curious and looked into my Amazon Orders to see when I bought it. I bought the watch in 2010 and it's 2017 now. So AT LEAST 7 years, because the watch still works fine. I will say though, while I did wear the watch when I first bought it (for about 6 months) I then bought another watch that I started to wear and have rarely worn this watch since. I still like the watch but for whatever reason have not been actively wearing it. So the next big question is:HOW HAS IT BEEN STORED FOR THE PAST 6+ YEARS???I figured it would be better for the battery if the watch stayed fully charged. So for the past 6+ years it has ALWAYS been near a light source. Never in direct sunlight though. I've always had the face pointed towards a window somewhere between 4-10 feet with lots of light light.I'm really curious how long it will last now. In the future I will try and remember to post updates if I remember. I'll also try to remember when to post when it eventually dies out.

scared and scratched. it's been my trustworthy adventure buddy for so long I had forgot when I purchased it. if I lost this watch, I would replace it with the same model without hesitation.

udents, who notice most things, and maybe one student has commented on the new watch. It works with anything I wear for work typically, although I plan to wear a stainless watch when I have to dress up in a suit. Not flashy, but certainly not ugly.Features - for the price, features are excellent and reasonably simple to use. Multiple alarms, including one "snoozable" alarm, radio time keeping which is updated nightly, solar charged battery, stopwatch precise to hundredths, countdown time, secondary time zone, for when traveling. It's also got a day of the week and month/date display as well. 200 m water resistance, shock resistance, and a backlight display round out the watch's main features.Experience - extremely positive! The watch has updated the time every night through the radio. It keeps a record of when it was last updated so you can check. The solar battery indicator was on "mid" when I received it, and stayed that way for a couple of weeks. After a day of yard work and watching a soccer game in the sun it moved to high level charge, where it's been ever since.Summary - excellent, worry free watch. Keeps accurate time, date, and month with a few other features. Would purchase again and recommend to a friend.
